Apply Silicone Caulk Around Gutter Profile

Reassemble Joint with Clips Back in Place

Repairing a Leaking Gutter

Gutter joints, whether sealed with a rubber gasket or sealant, will deteriorate over time and leak. The repair shown here uses gutter or silicone caulk. For gutters without joints, cut out the damaged section and replace it with a piece that is at least 2 in (5 cm) longer.

Materials and Tools:
cloth
gutter or silicone caulk
caulk gun

Disassemble the gutter joint by unclipping the gutter length from the joint clip (Image 1).

Remove the adjacent length of gutter to give you clear access to the internal profile of the joint clip (Image 2).

Dust out the joint, making sure that it is clean and dry (Image 3).

Apply gutter or silicone caulk around the edge of the gutter's profile (Image 4).

Reassemble the joint, fixing the clips securely back in place (Image 5).

Wipe away any excess caulk with a cloth.

Other Causes of Leaks

The gutter might be blocked and overflowing. Unblock it to fix the problem.

Loose attachments may cause sagging and overflowing. Fix as for a downspout.

A gutter needs a slope to drain efficiently. Check whether it needs adjusting to the correct angle.

Fixing a Loose Downspout

If downspout brackets become loose, joints in the pipe may fracture and cause water to run down the building. This may cause water infiltration problems, so loose pipes should be reattached immediately.

Materials and Tools:drill
suitable fasteners and wall plugs

Slide the loose downspout bracket to slightly above or below its previous position (Imags 1).

Hold the bracket in place, and mark where the new fasteners will need to go. Then drill pilot holes (Image 2).

Attach the bracket with the appropriate fasteners. Use wall plugs on masonry (Image 3).
